Game Mechanics and Modes

The game features sixteen numbered panels hiding either 2 or 4 uniformly shuffled mines. Players select the mine count and stake while idle, then click Open cabinet to deduct the stake. Clicking a panel reveals a safe space or a mine. A mine ends the round with zero return. Manual collection is allowed after the first or second safe panel. The third safe panel triggers automatic collection. There is no positional advantage to any panel.
03

Payouts and Settlement

Gross return includes the stake and is calculated as the captured stake multiplied by the survival probability inverse, adjusted by a 0.95 factor. The system preserves fractional carry in localStorage, adding it to the next successful settlement. Losing rounds retain this fraction. Net profit is the gross return minus the initial stake. Settlement uses full JavaScript precision, though display shows six decimals.
04

Wallet and Balance Rules

The initial balance is 1000 virtual coins. A captured stake is deducted immediately upon starting. Manual balance restoration to 1000 is available only when idle and the balance is below 10. This sets the balance rather than adding to it. Reloading the page drops the unfinished board with no refund or resume, preserving the post-debit balance and fractional carry. Manual restoration also clears the fractional carry to zero.
